Contact forms can as well, usually they seem to get forwarded to the IT department if they look like they have IT stuff in them, and I've had reasonable success getting hold of the right people that way.
Do you know if this is generally an in-house position for companies that use third party platforms?
I ask because Workday has been the absolute bane of my indexing existence, and I suspect they make it hard so they can own distribution of jobs to approved search engines. (Makes it easier to upcharge that way, I suppose.)
If the administrator for the job site is the Workday customer (i.e. Qualcomm or NXP or whoever is using Workday to host their job ads), I'd suspect I'd have a chance at getting a better way to index their jobs. (My god, I'd love API access if that's a thing I can get. I'd be a fly on the wall in most cases - one index a day is plenty for my purposes!)
How do you typically find contact info for someone like that?
I'm running very generous politeness intervals at the moment to try and ensure I'm not a nuisance - one query every two seconds.
